Underwear can be worn directly on the outside of the body-shaping pants, just take off your underwear when you go to the toilet, so you don't have to take off your body-shaping pants or pull hard. That's so sweet.
What's more, the crotch-less body-shaping pants in his family are more elastic and seamless? It is more convenient to put on and take off than ordinary tight-fitting pants. Anyway, I've been wearing his body-shaping pants since I gave birth.
